MOST NOTEWORTHY: Lehman, Cirrus Logic and Heinz were today's noteworthy upgrades:
- Citigroup upgraded shares of Lehman Brothers (NYSE: LEH) to Buy from Hold on valuation, as they see an "extremely attractive entry point" at current levels. They believe the company's profitable quarter in a tough environment, the Fed's actions to provide liquidity and management's track record all provide downside protection.
- Thomas Weisel upgraded shares of Cirrus Logic (NASDAQ: CRUS) to Overweight from Market Weight as they believe Wolfson Microelectronics' contract bid loss with a major tier-1 customer signals potential share gain for CRUS in the portable media player segment. They raised their target to $8.00 from $5.50 on the news.
- Heinz (NYSE: HNZ) was raised to Outperform from Market Perform at Bernstein as they expect the company to post solid growth going forward.
